GAS-BURNER'.

SPECIFICATION forming nart` of Letters Patent No. 660,933, dated October 30, 1900.

Application ined April 21, 1900.

To @ZZ whom t may concern:

Be it known that I, THEODORE ELIAS SINN- BERG, engineer, a subject of the Emperor of' Russia, and a resident of 54 Vicarage road,

Canlberwell, London, England, have invented new and useful Improvements in Gas-Burners, of which the following is a specification.

My invention relates to improvements in atmospheric gas-burners used for incandescent lighting, and has for its objectto enable the gas-supply and air-supply to be regulated both absolutely and also relatively to one another, so as to secure the best possible result in illumination.

The invention has also for its object to enable an ordinary luminous flame to be temporarily obtained without removing the atmospheric burnershould the incandescent mantle become unserviceable when a new one is not at hand for the purpose of renewal.

The invention consists in the particular construction and arrangement of parts, as, hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, wherein- Figure l is an axial vertical section of av complete atmospheric burner provided with independent air and gas valves. Figs. 2 and 3 show axial sections of two forms of burner attachment adapted to be fitted on the head of the incandescent burner for burning'gas without previous admiXtnre of air.

According to my invention the lower end of the mixing-tube A, wherein the streams of gas and air are intimately mingled on their way to the ignition-orifice, forms the seat for a disk valve B, mountedA upon a nut C, screwing upon a threaded part of the gas-supply tube D, so as to be capable of being raised or lowered at will for the purpose of regulating the admission ofair by varying the area of the annular opening a, between the edge of the valve and its seat in the bottom of the mixing-tube A. The upper end d of the gassupply tube D A'isnot closed, as usual, by a perforated diaphragm, (usually called an injector,) but is open and adapted to forni the seat for a conical'valve E, whereby the area of the gas-emission aperture may be varied Serial No. 13,722. I(No model.)

such that the nuts G and F are both readily accessible for purposes of independent adjustment of the valves B and E.

The valve E depends from the center of the dome-shaped upper end of the tu be G,\vhich is perforated, as at g, tov permit the exit of the gas,which is emitted beneath an upwardlyconvergent nozzle e, fitted over the upper end of the tube Gfor the purpose of directing the issuing gas in the form of' a jet upwardly and axially through the mixing-tube A, so as to produce byinduction a. current of air through the air-valve opening d. rlhe tube G is cylindrical, and the disk valve B makes a working fit about it, so that no air can enter the tube A between the valve B and tube G. The disk valve B is connectedwith the nut C by means of spider-arms b, affording free access to the tube G for the purpose of effecting the adjustment of' the valve E, the mixing-tube A being likewise supported by spider-arms d', attached to the lower end of the gas-supply tube D.

By the above-described construction the burner can be readily adjusted whenever necessary without removal from the gas-fitting to suit any pressure of gas, thus enabling the best possible illuminating effect to be obtained from the mantle and enabling what is known as intensified gas-lighting to be obtained with gas of the ordinary low pressure without the employment of a compressor. By this construction also the air-supply may be entirely shut oc by closing the valve B, so that if the mantle is broken and another is not available the gas alone may be burned by fitting on the head H of the burner one or.

other of the burners shown in Figs. 2 and 3.

The burner shown in Fig. 2 is an ordinary bats-wing or fish-tail nipple I, carried by a cap J, adapted to screw onto the head H ofthe mixing-tube A, while the burner shown in Fig. 3 is also a cap K, adapted to be screwed on the head H and provided with an annular series of minute orifices o,whence the gas issues and is burned as with an ordinary ring burner. The cap K carries a gallery supporting a glasshowl or short chimney L and arms m, supportingl a refieetor M.

I claim- I. In an atmospheric burner for incandescent lighting, the combination with the gassupply tube, of a gas-regulating valve and of ine-ans of adjusting.,r said valve and of direct.- iner the issuing jet of gas, said means consisting.r of a tube adapted to screwupon the gassupply tube and having: an apertured upper end to which the valve is fixed, thesaid tube beinel surmounted by a jetdirecting nozzle substantially as specified. p

'2. In an atmospheric burner, the coinbination with the gas and air mixing' tube and `with an independently-adjustable `valve for regulating the gas-supply, of a disk valve adapted to close against'. a seat at the lower end of the lnixing-tube, and carried by a nut. screwingr on a threaded part of the gas-supply tube for the purpose of regulating the admission of air to the inixingehamber, substantially as specified.

3. The combination with an atmospheric gas-burner provided with a Valve controlling the admission of' air to the lower end ofthe mixing-tube and around the gas-supply, ofa supplementary burner adapted to be fitted onto the head of the atniospherio burner in lieu of the mantle and mantle-support, and adapted for bnrninft,r gas nnmixed with air, substantially as specified.

ll. In an atmospheric burner, the combination with a `as-supply tube having an open upper end, of a tube screwing on the gassupply and havingadome-shaped perforated upper end, a plugwalve depending.: from the upper end of the tube and adapted to enter the gas-supply tube, and a iet-nozzle secured to the upper end of the valve-carrying tube, substantially as described.

5. In an atmospheric burner, the comlgiination with a mixing-tube, and a gas-supply tube, of a valve for regulating the admission of air tothe lower end of the mixing-tube, a tube adjustably mounted on the ,eas-supply tube and projectinp` through the said Valve, the upper end of the tube beingperforated, a valve secured to the inner face of the top of the said tube and adapted to regulate the How of gas through the gassu pply tube, and a jetnozzle secured to the upper end of the valvecarrying tube, substantially as described.

G. In an atmospheric burner, the combination `with a xnixin -tube, and a gas-supply tube, of atdisk valve adjustably supported on the eas-supply tube and adapted to regulate the admission of air to the mixing-tube, of a supplementary burner adapted to be secured to the head of the mixing-tube in lieu of the mantle and mantle-support., substantially as described.

7. Anattmospheric burner, consisting` of a mixing-tubeharing a valve-seat at its lower end, a screw-threaded .,assupply tube having open upper end, a disk Valve adapted to be seated on the seat of the mixing-tube, a nut onthe gassupplytubeaudtprovided with arms secured to said valve, a tube screwing on the gas-supplttube and having its upper end projecting.;r through `the disk Valve and provided with perforations, a plug-valve depending from the top of the tube and adapted to .enter the gas-supply tube, a jet-nozzle secured to the upper end of the tube Carryinglr the plug-valve, and interchangeable burners for the mixing tube, substantially as described.

R. In an atmospheric burner7 the combination with a mixingtnbe, and a gas-supply pipe, of a `valve for closing the lower end of themixing-chamber, and a `valve for closing `the upper end of` the supply-pipe, said Valves THEODO RE ELIAS SINN BERG.
